FILING-CASE.

SPECIFICATION forming part of Letters Patent No. 766,285, dated August 2, 1904.

Application filed April 20, 1903.

To all whom it may concern.-

Beitknown that I, BaRruoLn Pmosu, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filing-Cases, of which the following is a specification.

My invention relates to improvements in filing-cases of the card-index-tile type.

The object of my invention is to provide a simple, inexpensive, and effective device for securely holding the files in position, while permitting of ready disengagement. These and such other objects as may hereinafter appear are attained by the devices shown in the accompanying drawings, in which-- Figure 1 is a plan view of a filing-ease fitted with my improvements. Fig. 2 is an enlarged detail showing the side of the case and a part of the followerln'oken away. Fig. 3 is a sectional plan viewon the line 3 3 of 2 looking in the direction indicated by the arrows. Fig. l is a front elevation of the follower. Fig. 5 is a sectional plan view of a modification, and Fig. 6 shows another modification.

Like letters of reference indicate the same parts in the several figures of the drawings.

Referring by letter to the accompanying drawings. A indicates a filing-case in the form of a box containing files or cards B. which are held in place within the box by thefollower C.

The special feature of my invention relates to the construction and operation of this follower, which preferably comprises two sectionsCC, which are provided with oppositclydiverging faces 0 c and are hinged together at their adjacent edges by any familiar form of spring-hinge D, which is so constructed as to normally hold the sections C C away from each other. The sections C C composing the follower are so proportioned with relation to the casing that the outer faces E E of the sections will normally be held in frictional contact with the sides of the casing by the tension of the spring-hinge D. Preferably the outer faces E E are of such contour that when the parts are in normal position said faces E E will be parallel with the inner faces of the sides of the casingA, with which they are in contact. The front faces of the sections C Serial No. 153,449. (No model.)

are preferably so formed as to recede backwardly from the point where the scctionsC C are hinged together, so that the expansive pressure of the confined cards will be principally exerted against the inner corners of the sections C, so as to tend to supplement the action of the spring in spreading-said sections apart, and so in holding the faces E in frictional contact with the inner faces of the sides of the casing A; butsuch feature is not essential, as my device is operative without such supplemental spreading action.

For convenience in handling and operation the section C may be provided with recesses or grooves (jr, affording a convenient hold for bringing the sections together, and thus releasing them from engagement with the sides of the casing A and with clips H, which facilitate the retraction of the follower when disengaged from the casing.

In Fig. 5 I have shown a modification of my invention, in which the hinge D and the spring (Z are separate from each other, and the hinge l) is moved back from the forward edge of the follower, so that the expansive pressure of the files exerted against the forward inner corners of the sections C C, which will constitute the pointof greatest pressure, will be more effective in holding the faces E E in frictional contact with the sides of the easing. In fact, while I prefer using the spring to insure this locking contact between the faces E E and the sides of the casing it is possible to dispense with the spring and to rely upon the expansive pressure of the files to insure this locking contact.

In Fig. 6 I have shown another modification, in which the follower is composed of three parts, the clampingsections C being connected by spring-hinges upon opposite sides of the body-block C.

The modifications illustrated are merely suggestive of some of the variations which may be made in the details of my construction without departing from the spirit of my invention.

I claim 1. The combination with a casing, of a follower comprising two sections hinged together, and compressible means arranged to spread said sections apart and to normally hold the outer broad faces of said sections directly in locking contact with the inner faces of the sides of the casing.

2. In a filing-case, the combination with a casing, of a follower composed of sections hinged together and arranged when spread apart to be in locking contact with a part of the casing, the front of said follower receding so that the pressure of the files confined between the follower and the end of the casing will tend to spread the sections of the follower to locked position. Y

3. The combination with a casing, of a follower comprising two sections mounted in pivotal relation to each other, the front faces of said sections being arranged to recede in such a manner that the expansive pressure of the files confined between said follower and the end of the casing will tend to hold said sections in looking contact with the sides of said casing.

4:. The combination with a casing, of a follower comprising two sections provided with oppositely-disposed diverging faces, a hinge for securing said sections in pivotal relation to each other, and a spring arranged to normally and yieldingly hold said sections apart from each other and in looking contact with the sides of said casing, the front faces of said sections being arranged to so recede that the expansive pressure of the files confined between the follower and the end of the casing will tend to supplement the action of said spring in holding said sections in locking con.

tact with the sides of said casing.
